    Default 100% disk usage, so slow! Help me!

    Hello,

    My disk usage is always really high, normally at 100%! In task manager, when I sort the disk usage by percentage, the highest process is usually around 2% and everything else <1%. I'm no computer whiz by any means, but I don't really understand how or why this is happening, especially with Chrome being the only program open (and background processes of course, but they don't seem to be the issue??).
    Screenshot here: http://imgur.com/5o8tFBd
    Everything is so slow. Like, frustratingly slow. Why? This is driving me crazy now, it's a struggle to have more than one program open.

    I've googled this issue many times but still have not found a fix. Some people with this issue said this happened after Windows 8 updates but I'm pretty sure that's not the case here.. I've had the laptop 3ish years and I'm pretty sure it's always been like this (well, for aaaages anyway, I've just put up with it). My laptop is a Sony Vaio E Series. Intel Core i7. 4gb ram

    Things I've tried:
    I've run both Malwarebytes, Spybot, Sony's VAIO care/performance tools, disk defrag.
    Manually adjusting virtual memory space as per this suggestion: https://community.sony.com/t5/VAIO-S...p/57485/page/2

    Was running Windows 8 before, now upgraded to Windows 10 (thought it might help; didn't).
    Even typing here is lagging so much! Literally the only program I am running is Chrome, and Task Manager.

    Any help would seriously be much appreciated. Let me know if you need any more info.
    Hopefully it's a simple fix? Sorry to be a noob, like I said, I'm not too computer savvy and googling the issue didn't seem to help.

    Theres quite a few reasons why it goes to 100%, the main one by the looks of it in your case isn't the cause - System and Compressed Memory.

    Give this a go, works sometimes: Click on start, settings, system, notifications, and turn off everything. If it drops down to low number 0-4% then if you want enable one at a time to find out wheich one is causing it. Other wise leave them all off.

    Hi there,
    Thanks so much for your response. I've turned all notifications off but it doesn't seem to have helped anything unfortunately.
    Here's a new screenshot if that helps: http://i.imgur.com/4G5I5hk.jpg
    Any other suggestions?

    Post screen shots of the remainder of the Task Manager list, you may have to do several.

    What you can also try - just to check, right click the start button, from the list select Command prompt(Admin) in the window that opens type in sfc /scannow <Press Enter> Does it find any faults, fixed them, or found faults but cant fix them.

    No matter what it reports, when finished type in Dism /Online /Cleanup-Image /ScanHealth <press enter>

    What does it report ?

    Add to above: When running Dism /Online /Cleanup-Image /ScanHealth It may get to 20% and appear to hang/stop. It hasn't, just leave it alone ,it will suddenly jump to 80% + and finish

    Example:

    This is what a healthy system should report - changed colours & font, I got bored

    Here are the screenshots. Was very difficult as the processes move every second so could be missing some stuff. Also computer was so slow - screenshotting and saving images took 45 min which should have been a 5 min job. So not sure how accurate/helpful this will be.

    Will try the command prompt suggestion now and report back.

    It could just be a failing HD.
    HD's can sometimes go really slow when they go bad, rare but Ive seen a a few do that.
    Add up all the disk usages & see the total MB/s is


    Could also be your system is due for a good clean out/decrap .
    MSconfig & disable all startups & non MS services & see if that helps (just as a test)

    The first two in the list are sometimes high, and cant really be disabled, often caused by some sort of corruptions -- This PC was liek that,o nly way to fix was a complete reinstall, worked fine after that, they should be in the 0.0 -0.3 Range.

    There is a lot of crap running on startup, not needed - On task manager - Select the Startup Tab, if you have to, re-size the window to include everything, post a screen shot and we can disable all the rubbish - not needed items. All those small bits add up.

    If that doesn't work, then have a read of this forum 10_high_disk_usage_100, its long, and theres quite a few reasons given as well as the first one ( with replies) , As mentioned earlier, theres LOTS of reasons why you get 100% disk usage. Its a matter of eliminating one at a time till you find the one. Also have a read of how-to-fix-100-disk-usage-in-windows-10

    you can also try running https://technet.microsoft.com/en-us/...rocessexplorer it may show whats sucking the usage. (high reading)

    Its a bit hard to pin point when you we dont have the computer in front of us, so its trial and error.

    Thanks so much for the responses.

    Okay so I've tried all of your suggestions, all the suggestions from the reddit thread and the other links. Every single one, nothing has helped so far.

    The scan was all ok. Image: http://i.imgur.com/TTC2vTF.jpg

    I ran chkdsk in prompt, it said there were errors. I then did "chkdsk /f" into command prompt to fix and repaired upon restart. Took screenshot of the prompt if that helps.

    Here are my processes on startup: http://imgur.com/a/UyAPt

    The process explorer app shows the following results (one image sorted by CPU and the other by working Set): http://imgur.com/a/Jc7SY
